Jubilee line

The Jubilee line is a London Underground line that runs between Stanmore in suburban north-west London and Stratford in east London, via the West End, South Bank and Docklands. Opened in 1979, it is the newest line on the Underground network, although some sections of track date back to 1932 and some stations to 1879.

The western section of the line between Stanmore and Baker Street was previously a branch of the Metropolitan line until 1939 and later a branch of the Bakerloo line until 1979, while the newly built line was completed in two major sections: initially in 1979 to Charing Cross, then in 1999 with an extension to Stratford. The later stations are larger and have special safety features, both aspects being attempts to future-proof the line. Following the extension to east London, serving areas once poorly connected to the Underground, the line has seen a huge growth in passenger numbers and is the fourth-busiest on the network (after the Northern, Victoria and Central lines), with over 276 million passenger journeys in 2019.
